Move AJAX health check to be intermittent to prevent spamming endpoint, and locking up Moodle session. #170

Closed andrewmadden closed 2 years ago

andrewmadden commented 3 years ago

Modify lib/panopto_data.php:is_server_alive to keep track of last health check and when the next health check should be requested.

At scale, some clients were reporting that end users were receiving 500 errors. We discovered that it was due to an Ajax request failing to make a connection to a remote Panopto server and timing out.

Instead of all students needing to make the request to check the health of the remote server, the health check can be made periodically (30 seconds by default), and the result cached in Moodle and used by all other users for that period.
